For one, you've got a bunch of unnecessary capitalization in your SCProcedures.

Any and all interaction with SCP-3472 is to be in a controlled setting and Class D personnel are the only ones permitted access to SCP-3472.

This is basically assumed for most dangerous skips.

As of incident 3472-a all testing involving SCP-3472 is suspended permanently, see incident 3472-a, however tests involving SCP-3472-1 are allowed under strict supervision.

This sentence contradicts itself. All testing is suspended, except during testing?

SCP-3472 is a sheet of aluminum foil 12 inches in length by 13 inches in width with various cuts and holes on the sheet.

We use SI units, not imperial. This needs to be converted, and I'd personally suggest looking up standardized measurements for aluminum foil in europe to avoid just converting 12 inches to Cm.

SCP-3472 appears to be completely flat and when viewed under an electron microscope, it appears to show this feature despite multiple scars of bends and cuts visible on the sheet.

Does it appear to be flat, or is it flat? Also, the entire half of the sentence after the comma has awkward and non-clinical language. "it appears to show this feature" doesn't really say anything. If it has a property, it is has it.

When SCP-3472 is bent, ripped, or any form of damage is made to its surface it enters a “rage” state in which it attacks the person who caused damage to its surface by using its edges to cut the person’s throat, and attempting to cut off the person’s oxygen supply by covering the nasal and oral passageways.

Without going in to it too much, the entire idea of a "rage" state is very silly, and isn't the kind of tone that we encourage anymore. Beyond the use of a series 1 trope, rage is an emotion. Aluminum can't have emotion.

Also beyond that, this is a run on sentence. Even if all of these issues were fixed, this is a…very silly concept.

The rest of your article involves non-clinical language, and very conversational tone.

Specific highlights:

even if they have had no prior contact, though the attacks aren’t as bad as when SCP-3472 is bent.

The only thing that appears to calm it during this phase is if it is flattened using SCP-3472-1.

You need to say what SCP-3472-1 is before talking about it in the description.

See addendum SCP-3472-a-254 to see proper flattening protocols. SCP-3472-1 is a gold Crayola brand colored pencil that shows no other anomalous properties other than it is the only object known to calm SCP-3472 when in its agitated state.

I'd like you to read this sentence to yourself. Is this something a scientist would say to another scientist about an anomalous object?

When SCP-3472 was ripped it responded immediately and slashed D-50296’s throat and was seen slashing until D-50296 expired.

Slashing is not a clinical term for lacerate.

Your interview has a strange format.

Why is all of the text in square braces? Why would a doctor tell a PoI that they're being Amnesticized? HOw was this person discovered?

Why isn't the interview in another addendum?

Overall, you've got major issues. This object has a lot of series 1 tropes that we try to avoid these days, and overall has little to no narrative.

It's a peice of foil that kills you…because some guy rubbed a pencil on it. SCP articles are a vehicle for a story. It's not enough to just have something anomalous. You need to come up with some kind of narrative, or at least a point, beyond "thing what kills you".

Overall this needs a lot of work. I'd say at this point, this is basically just a skeleton concept without much of an article around it, and should probably be overhauled.

"SCP-3472 is to be contained in a standard Safe-class Anomalous Item containment locker with SCP-3472-1 and is to be removed only for testing or for routine flattening with SCP-3472-1."

You could shorten the "standard-safe-class-anomalous-item-containment-locker" with "standard containment locker", and I wouldn't think it would be a good idea to put them together, even if they are safe, but I don't know about that, so I guess you can keep it.

"Any and all interaction"

'any interaction'

"SCP-3472 is to be in a controlled setting"

'controlled setting' - What does this mean? What temperature? Wet or dry?

"Class D personnel are the only ones permitted access to SCP-3472."

I think you worded this incorrectly. It seems as if you would just let Class D's out of their cells to play with this thing at any time in any moment. I think you mean that Class D's are the only ones which can test the item, which would be quite obvious anyways.

There is nothing wrong with this, except the non-capitalised a for 3472-A, but this should be added earlier in the draft, as you already said that Class D's can have 'access' to SCP-3472.

"SCP-3472 is a sheet of aluminum foil 12 inches in length by 13 inches in width with various cuts and holes on the sheet."

It might be just me, but I would reword this to "SCP-3472 is a sheet of aluminum foil, 12 inches in length, and 13 inches in width, containing obvious physical damage, such as cuts and holes."

"SCP-3472 appears to be completely flat and when viewed under an electron microscope, it appears to show this feature despite multiple scars of bends and cuts visible on the sheet."

So its just… Flat? How flat? If its too flat, it would of been destroyed because the small amount of thickness.

"When SCP-3472 is bent, ripped, or any form of damage is made to its surface it enters a “rage” state"

Now this sounds silly. A piece of aluminum foil which enters a rage state. I would reword this, as it sounds unclinical due to improper description. I would write; "If SCP-3472 is in any way bent, ripped, or damaged, the foil begins to anomalously reanimate."

"in which it attacks the person who caused damage to its surface by using its edges to cut the person’s throat, and attempting to cut off the person’s oxygen supply by covering the nasal and oral passageways."

'The main thing it does is, be suprised! Kills you!' If this is the main idea of the SCP, I can see it already being downvoted into the pits of oblivion, because its just a thing which kills you. And it kills you in a boring way, so it just adds more to the blandness.

"It wasn’t shown to have this behavior until ██/██/████, and it is presumed to learn the many weaknesses of humans from the victims of SCP-3472."

'SCP-3472 did not show such behaviour until' - By the way, you are writing about SCP-3472, so I am confused. You are saying that the object itself learned killing humans from it already killing humans, which sounds like its breaking multiple time laws.

"If SCP-3472 is left alone for 72 hours or longer it will become animate, using its corners as “legs”, and begins to show signs of agitation. It also shows aggression towards people, even if they have had no prior contact, though the attacks aren’t as bad as when SCP-3472 is bent."

Only people? Like, what if a sheep was near? Also, you only refer to it when it is being bent, not damaged in a way, as bending does come in a form of damage.

"The only thing that appears to calm it during this phase is if it is flattened using SCP-3472-1."

And the Foundation personnel knows this by? Its not easy calming down a triggered aluminum foil which has a mind of its own and wants to cut your neck by folding it with what, a Crayola pencil?

"Using any other object to flatten SCP-3472 will not cause it to stop animating."

Even though, if you flatten it with an object which covers its whole body, it will just be stuck.

"to calm SCP-3472 when in its agitated state."

Same with the last one, its kind of like you are referring that SCP-3472 is a human, as aluminum foils don't have states of agitation.

"and slashed D-50296’s throat and was seen slashing until D-50296 expired."

I wouldn't put expired, as it sounds odd in this sentence. I would write "until D-50296 ceased to live."

"SCP-3472 was seen making its way to Dr. ██████ Who was the doctor that ordered D-50296 to rip SCP-3472 before becoming docile. All testing involving SCP-3472 has been suspended indefinitely."

Unneeded capitalisation at "who". By the way, why would the doctor be in the cell in the first place? Its risking people who are important to the Foundation for a stupid reason. Last thing, what happened to the doctor? You just end it as being ended suddenly.

"[ok, I’ll have the guards’ take you to the med bay to be administered amnestics.]"

Remove all of the []'s, as they are unneeded. Also, why does the creator of the thing need to be administered amnestics at the Medical Bay? He just created this thing, its now contained, and what? Its not a dangerous infohazard or anything. Just leave him after an interview or two, and it would be done. No amnestics needed.

"[Let’s just say, the foundation’s purpose is to be out of the public eye.]"

1. That is the point of the Foundation.
2. Capitalise Foundation; its a group.
3. Even if this thing would breach containment, it would go no where. Giving amnestics could be useful to eliminate his memory of that thing, but not in a sense that he/she could be endangering lives.

"Dr. Andrew has suggested that SCP-3472-1 is actually the true SCP and SCP-3472 is the -1 and has requested testing using SCP-3472-1 and a normal sheet of aluminum foil."

You said that this thing was not anomalous except that it can stop SCP-3472 if used correctly, and SCP-3472 is the only anomalous thing to be real. This wouldn't be logical, as the main SCP would be just a pencil which can do an anomalous thing.

"Due to the risk of making another instance of SCP-3472, the test is pending 05 approval."

But who the hell would roll a piece of foil with a pencil for a week or two? Also, its O5. Also also, there is no need bothering them, as this can be approved by Doctor Andrew.

The main concept is extremely flat and boring. A thing which gets angry if you do something to it and it kills you isn't something unique or thought-intriguing. Its a really bland idea, and can't even be fixed with huge amounts of execution.
